wu-ftpd replacement for ftpd

by Jeffrey D. Ang » Wed, 17 May 1995 04:00:00

Thanks to Bill at Celestial.com for pointing this one out to me.

However, I am having a few minor problems setting it up. SLowly I am finding
out (from repeated RTFM'ing) where to put the messages and so forth, but how
do I recover from mistakenly invoking the ftpshut command?

To paraphrase Radio Shack, You have answers, I have questions...

Thanks

1. in.ftpd zombie problem with wu-ftpd on RH6

We're using wu-ftpd-2.5.0-2 on RedHat 6.0. The server is working
fine, but we have noticed the following problem:

After several days of operation, there will be many 'leftover'
in.ftpds. We allow 100 users at a time and this is resulting in users
being denied access to the site even though there are only 3-4 active
connections.

If you do a ftpshut followed by a killall in.ftpd, then all is fine
for several more days.

Once the problem develops, a ps shows:

# ps ax | grep in.ftpd
